What a Social Security Lock Does and Why You Might Want One

A Social Security lock is a free service that stops anyone — including you — from opening new credit accounts using your Social Security number. When a lock is active, lenders cannot pull your credit report without first removing the lock, which requires a PIN only you know. This makes it much harder for someone who has stolen your number to take out loans, credit cards, or phone plans in your name.

You do not need to have been a victim of identity theft to use a lock. Many people set one up as a preventive step, especially if they are concerned about data breaches or if their Social Security number has been exposed. The lock stays in place until you remove it yourself, and you can turn it on and off as often as you need — for example, removing it temporarily when you are shopping for a mortgage or car loan, then putting it back afterward.

Key Takeaways

  • You can lock your Social Security number for free through the official Social Security Administration website at ssa.gov/myaccount, which is the only government source for this service.
  • The lock requires you to create a my Social Security account with your name, date of birth, Social Security number, and an email address or phone number for verification.
  • Once locked, lenders cannot access your credit report without first contacting you to remove the lock using a PIN that only you receive.
  • You can unlock your number temporarily or permanently at any time through the same account, and there are no fees or credit checks involved.

Creating Your my Social Security Account

Before you can lock your number, you need a my Social Security account on the official Social Security Administration website. Go to ssa.gov/myaccount and click "Create an account." You will be asked for your name, date of birth, Social Security number, and either an email address or phone number. The Social Security Administration will send a verification code to whichever contact method you choose.

Enter that code to confirm your identity, then create a username and password. Your username can be anything you choose — it does not have to be your real name. Make your password strong: at least 12 characters, with uppercase and lowercase letters, numbers, and symbols. Write down your username and password somewhere safe, or use a password manager. If you lose access to your account later, you will have to go through identity verification again to regain it.

Once your account is set up, you will see a dashboard with options including "Lock my Social Security number." This is where you start the locking process.

Locking Your Number and Receiving Your PIN

From your my Social Security dashboard, select "Lock my Social Security number." The system will ask you to confirm your identity one more time using information only you would know — usually questions about your credit history or personal details. Answer these questions accurately.

After you pass this verification, your number is locked when ready. The Social Security Administration will send you a Personal Identification Number (PIN) by mail to the address on file with them. This PIN is the only way anyone — including you — can unlock your number or open new credit accounts while the lock is active. Keep this PIN in a safe place, separate from your Social Security card and other documents.

The PIN typically arrives within one to two weeks. Until it arrives, your lock is active but you will not yet have the PIN needed to unlock it if you need to. If you do not receive your PIN within three weeks, contact the Social Security Administration at 1-800-772-1213 to request a replacement.

Unlocking Your Number When You Need Credit

If you want to open a new credit account — such as explore for a mortgage, car loan, or credit card — you will need to unlock your number first. Lenders cannot pull your credit report while a lock is active, so the process will be rejected or delayed.

Log into your my Social Security account and select "Unlock my Social Security number." Enter your PIN when prompted. Your number will be unlocked when ready, and lenders can then access your credit report. You can set a temporary unlock that lasts a specific number of days (usually 1 to 30 days), or you can unlock it permanently until you lock it again yourself.

Once you have completed your credit process or loan process, log back in and lock your number again. You do not need a new PIN each time — the same PIN works for all future locks and unlocks.

What Happens When Your Number Is Locked

When your lock is active, a lender or creditor who tries to pull your credit report will see a message that your number is locked. They cannot proceed with opening an account without first contacting you. Some lenders will call or email you to ask if you want to unlock your number; others will straightforward deny the process.

This means that if someone steals your Social Security number and tries to open a credit card or take out a loan, they will hit the lock and be unable to continue. They cannot call the Social Security Administration to remove it — only you can, using your PIN. This is what makes the lock effective: it puts the power to unlock in your hands alone.

A lock does not affect your existing accounts, your credit score, or your ability to work. It only prevents new accounts from being opened. You can still check your credit report, explore for jobs, or use your Social Security number for legitimate purposes.

Protecting Your PIN and Account

Your PIN is as important as your Social Security number itself. If someone gets your PIN, they can unlock your number and open accounts in your name. Store your PIN in a safe place — a locked drawer, a safe, or a password manager — separate from your Social Security card and other documents.

Do not share your PIN with anyone, including family members, unless you fully trust them and have a specific reason. The Social Security Administration will never ask you for your PIN by phone, email, or mail. If someone contacts you claiming to be from the Social Security Administration and asks for your PIN, it is a scam.

If you forget your PIN, you can request a new one through your my Social Security account. You will have to verify your identity again, and a new PIN will be mailed to you. If you suspect your PIN has been stolen, contact the Social Security Administration when ready at 1-800-772-1213.

Frequently Asked Questions

Can I lock my Social Security number if I do not have a my Social Security account yet?

No. You must create a my Social Security account first at ssa.gov/myaccount. The account creation process takes about 10 minutes and requires your name, date of birth, Social Security number, and a way to verify your identity (email or phone). Once your account is set up, you can lock your number when ready.

What if I lose my PIN?

You can request a replacement PIN through your my Social Security account by answering identity verification questions. A new PIN will be mailed to you within one to two weeks. If you cannot access your account, call the Social Security Administration at 1-800-772-1213 and they can help you recover it.

Does locking my Social Security number cost anything?

No. The lock and PIN are completely free. The Social Security Administration does not charge for this service. Be cautious of websites or services that claim to lock your number for a fee — those are not official and may be scams.

Can I lock my child's Social Security number?

Yes, but the process is different. You must create a my Social Security account using your child's information and verify your relationship to them. Contact the Social Security Administration at 1-800-772-1213 for guidance on locking a minor's number, as the steps vary depending on your child's age.

Will a lock prevent me from getting a job?

No. A lock only affects credit applications. Employers can still verify your Social Security number for employment purposes, and the lock will not interfere with payroll, taxes, or any work-related processes.
